20080285085 | Method for Controlling the Shapes of FM-AM Mixed Dots on a Multi-Bit Depth Imaging Apparatus - Disclosed is a method for controlling the shapes of FM-AM mixed halftone dots on the multi-bit depth imaging apparatus. In the prior art, since the reproduction of the shapes of the dots in various gradations is absolutely based on the theory of random error diffusion and is influenced by the dynamic controlling output mechanism for the multi-bit dots, it is hard to assure the controllability of the shapes of the dots in a certain gradation. Based on the prior art, the dynamic statistic algorithm with adjacent output gray levels is introduced to assure the controllability of the shapes of the dots and solve the problem of random change of the shapes of the dots due to the randomicity of the error diffusion.

In the prior art, since it is hard to avoid the impact of the error diffusion for the output apparatus to control the mixed dots with multi-bit imaging depth based on the error diffusion, the output of the mixed dots with multi-bit imaging depth cannot satisfy requirements of the apparatus. According to the method of the present invention, the dynamic algorithm for controlling the multi-bit mixed dots is used for screening based on the existing mixed screening process using dual-feedback error diffusion. Furthermore, multi-bit halftone images with high quality and rich gradations can be output by the multi-bit depth imaging apparatus. The method of the present invention can solve the phenomenon of sawtooth in the margins of the mixed dots output by the conventional single-bit apparatus and obtain the FM-AM mixed dots with the effect of high resolution and continuous gradations, which are output under low resolution. | 11-13-2008 |
